sorry but this photo is not clear
I am pretty sure the first thing we should do is to <span>integrate acceleration into velocity
And we will have: </span>


Then calculate v :

As you can see, velocity is zero and none of the objects is moving. It happens when <span> t=7/3 which means we can calculate this in the way we did (integrating) :
</span>

The product is <span>p(0) = 0 that makes us to reduce vector function to</span>
